Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2 – Summary of Significant Accounting Policies Basis of Presentation The Consolidated Financial Statements include the accounts of The Cigna Group and its consolidated subsidiaries. Intercompany transactions and accounts have been eliminated in consolidation. These Consolidated Financial Statements were prepared in conformity with accounting principles generally accepted in the United States of America ("GAAP"). Certain amounts in the Consolidated Statements of Cash Flows have been reclassified to conform to current year presentation and did not have a significant impact on our Consolidated Financial Statements. Amounts recorded in the Consolidated Financial Statements necessarily reflect management's estimates and assumptions about medical costs, investment, tax and receivable valuations, interest rates, and other factors. Significant estimates are discussed throughout these Notes; however, actual results could differ from those estimates. The impact of a change in estimate is generally included in earnings in the period of adjustment. These interim Consolidated Financial Statements are unaudited but include all adjustments (including normal recurring adjustments) necessary, in the opinion of management, for a fair statement of financial position and results of operations for the periods reported. The interim Consolidated Financial Statements and Notes should be read in conjunction with the Consolidated Financial Statements and Notes included in the 2024 Annual Report on Form 10-K ("2024 Form 10-K"). The Company has not included certain footnote disclosures that would substantially duplicate the disclosures contained in its 2024 Form 10-K, unless the information in those disclosures materially changed or is required by GAAP. The preparation of interim Consolidated Financial Statements necessarily relies heavily on estimates. This and other factors, including the seasonal nature of portions of the health care and related benefits business, as well as competitive and other market conditions, call for caution in estimating full-year results based on interim results of operations. Recent Accounting Pronouncements The Company's 2024 Form 10-K includes discussion of significant recent accounting pronouncements that either have impacted or may impact our financial statements in the future. There are no updates on significant accounting pronouncements recently adopted that have occurred since the Company filed its 2024 Form 10-K. There are no significant accounting pronouncements recently issued and not yet adopted that are expected to impact our operations or financial statements, with the exception of Accounting Standards Update 2025-06, Targeted Improvements to the Accounting for Internal-Use Software. In September 2025, the Financial Accounting Standards Board issued new guidance related to Targeted Improvements to the Accounting for Internal-Use Software (Subtopic 350-40), Accounting Standards Update ("ASU") 2025-06, which seeks to improve the operability of the recognition guidance considering different methods of software development, mainly more iterative methods. The guidance is required to be adopted January 1, 2028 with early adoption permitted, and transition options include prospective from the date of adoption as well as retrospective adoption. The Company is currently evaluating the impact of this guidance on our results of operations and financial position, as well as potential impacts to systems and controls.
